SNOW-PLOW.

SPECIFICATION forming part of Letters Patent No. 364,818, dated June 14-, 1887.

Application filed Se; tember29, 1886. Serial No. 214,564. (No model.)

To all whom. it may concern:

Be it known that I, OLIVER U. GUINAND, of Excelsior Springs, in the county of Clay and State of Missouri, have invented a new and Improved Snow-Plow, of which the following is a full, clear, and exact description.

, The object of my invention is to provide a new and improved snow-plow for clearing railroad-tracks by loading the snow from the drift upon the plow and removing the same to a convenient place for dumping.

The invention consists of various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts .in all the views.

Figure l is a longitudinal sectional elevation of myimprovement. Fig. 2 is a plan view of the same, parts being broken out; and Fig. 3- is a perspective view of the lower rear part of my improvement.

The snow-plow A is provided with a frame, B, mounted on Wheels 0, and has an inclined platform, D, which is provided in its front end,

on each side, with a segmental slide, E, which form a guide for the knife or end-gate-F, scoured to the lever-arms G, pivoted on the shaft H, mounted in suitable bearings on the platform D, and running across the same. A clearing-plow, I, having the curved sides I, is mounted on wheels 1 running on the vrails I, secured to the platform D, and is provided with an eye, 1*, through which passes a rope, J, running over the pulley J, which runs loose on the shaft H, and one end of the rope J is secured to the forward end of the draw-bar K, which is provided on its other end with the draw-head K, adapted to be coupled to the front end of the locomotive in any suitable manner. The rope J also passes over the pulley J", mounted on the upper end of the inclined platform D, and then passes downward and under a pulley, J mounted on the frame supporting the platform D, and then runs forward and is connected to the outer end of the draw-bar K. A grip, P, of any desired c011- struction, is mounted on the plow I and operates on the chain or rope J. The lower end of each lever-arm G is connected by means of the rod L with the sliding frame M, consisting of the side bars, M, and the slotted cross-beam M and is mounted to slide on the .rear part of the frame 13. The inner end of the drawbar K passes through the slotted cross-beam M of the frame M, and can be coupled to the same by the coupling-pin N, and the drawbar K can also be fastened or locked to the frame B by the coupling-pin O, which passes through that the forward sharp edge of the segmental guides E cut into the snow, which is then plowed off the track by the inclined sides of the clearing-plow I in the usual manner until the drift can no more be pushed aside. The coupling-pin N is then withdrawn, and the locomotive is backed so that the front end of the draw-bar K moves to the rear part *of the frame B. The grip P on the plow I is then put into operation so as to fasten the plow I to the rope J, and when the locomotive now moves forward the plow I is drawn up the inclined platform D to the position shown in dotted lines in Fig. 1.. The entire apparatus is then pushed into the snow-drift for a load, which settles on the inclined platform D. The grip P is then released from the chain or rope J, and the coupling-pin N is inserted, so as to couple the sliding frame M with the draw-bar K. The locomotive is then backed a short distance, (about four feet,) and thereby the snow-plow I remains in its position, but the cutter F swings downward to the front, as shown in dotted lines in Fig. 1, by the action of the rearwardly-sliding frame M, and the rods L acting on the arms G, carrying the said cutter. It will be seen that the load of snow on the platform D is now held in posi tion by the cutter or end-gate F and the snow-plow A is removed to a convenient place for unloading. As soon as the plow arrives at the desired dumping ground or place, the locomotive is forced to move forward, so that the frame M slides forward, whereby theknife or end-gate F is again raised to its normal position by the action ofthe rods L on the leverarms G, which carry the said gate. The coupllng-pin N is then again withdrawn, so as to uncouple the sliding frame M from the drawbarK, and the grip P is again set in operation, so as to couple the snow-plow I to the chain or rope J, and the locomotive then backs up or moves rearwardly, and the drawbar is pulled outward, which causes the clearingplow I to move downward on the inclined platform D, thereby pushing the snow off from the said platform. The plow I is held in its lower position by means of stays or braces in any suitable manner.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A snow-plow provided with an inclined platform,in combination with segmental guides on each side and a movable cutter or endgate, substantially as shown and described. 2. The combination,with aframe,of a clearing-plow mounted movably on an inclined platform, segmental guides attached to said platform, a swinging end-gate or cutter'on the sand segmental guides, and means for operating the said cutter or end-gate, substantially as shown and described.

3. The combination, with the frame of a snow-plo.w, of the sliding frame M, mounted on the said frame B, the connecting-rods L, the levenarms G, and the end-gate or cutter F, attached to the said leverarms, substantially as shown and described.

4. In a snow-plow, the combination, with the frame B, of the sliding frame M, the draw bar K, adapted to be coupled to the said frame M, the rods L, attached to the said frame M, the lever-arms G, and the end-gate or cutter F, attached to the said lever-arms G, substantially as shown and described.

. 5. The frame B and the inclined platform D, in combination with the plow I, the chain or rope J, adapted to be coupled to the said plow I by means of the grip I, and the drawbar K, sliding on the said frame B and connected with the said rope J, substantially as shown and described.

6. The frame 13, mounted on wheels, the in- J clined platform D, and'the segmental guides E, mounted on each side of the said platform D, in combination with the plow I, mounted to slide on the said platform D, the chain or rope J, adapted to be coupled to the said plow I, the draw-bar K, connected with the said rope J, the frame M, sliding on the frame I3 and adapted to be coupled to the said draw-bar K, the lever-arms Ur, connected to the said slid' ing frame M by the rods L, and the end-gate or cutter F, attached to the said lever-arms G, substantially as shown and described.
